VENTILATING RAILROAD-CARS, &C.

SPECIFICATION flming parl'. 0f Letters Patent NO. 229,72), (1a-bed July 6, 1880.

Y Application filed May 27, 1879.

To all whom it 'may concern Be it known that l, JOHN S. LLOYD, of Flemington, in the county of Hunterdon and State of New Jersey, have invented certain new and useful Improvements in Ventilating Railroad-Gars and Excl ndin g Smoke, Cinders, 85o., therefrom; rand I do hereby declare the following to be a full, clear, and exact description of the invention, 'such as will enable others skilled in the art vto which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification, in which- Figure l is a side elevation of an engine, tender, and car, partly in section, equipped with my improved Ventilating devices. Fig.

2 is an elevation, partly in section, of stove and air-supply pipe. Fig. Sis a sectional view of valve and inlet of air-supply pipe. Fig. 4 is a longitudinal vertical section of air-pipe couplings.

My invention has for its object to provide means for Ventilating railroad-cars; and my improvements consist in the peculiar construction and combination of parts, as hereinafter set forth,

Referring to the accompanying drawings, A indicates the engine, B the tender, and C a car, of a train to which my improvements are applied.

D represents a pipe extending from the front of the locomotive back to the tender and car, having coupling-connections, as .hereinafter set forth. The front end of said pipe has two Ways or openings, d d', with a damper or valve,- d2, which is under control of the .engineer in the cab by means of a rope, d3, proceeding thereto, as shown.

E is a blower in the path of the pipe D, and operated by a belt, e, and pulley e from the driving-shaft E of the engine. Ez represents a shifter for the belt c, whereby it may be moved to a loose pulley. Said blower is arranged to draw in the air through the openings d or d', and force the same back into the car C.

The couplings for the pipe D are composed as follows:

F represents a pipe flxedly sustained on the pipe D and having a shoulder or bead, f, and surrounded bya spiral spring, f.

G is a cylinder, into the end g of which pipe F passes, the opening g' in said end being of greater diameter than said pipe F, but of less diameter than its shoulder j'. g2 g3 are washers on either side of the head g.

H is a short threaded sleeve screwed into the opposite end of cylinder G, and provided with a stem, h, disk h', washer h?, and spring h3. When the stem his pushed inwardly the washer h is moved away from the head or seat g4. When not so pushed in the washer h2 seats on the ilange g4, and the valve is closed. rEhe stems h normally project from each of the cylinders G G; but when two come together they push each other in, opening the valves and permitting free passage for the air through pipe D and its couplings, as shown plainly in Fig. 3.

K K are iiarin g spring-arms attached to the cylinders G, forming guides and grapples for directing the ends of the stems L toward each other when the cars approach, and for holding said cylinders together when in contact.

The pipe D passes into the car C beneath the roof, and has valves for controlling the course of the air-currents therein.

By means of the valve L the air may be caused to pass down the branch D and around the stove L', being thereby heated, and then permitted to escape into the car from any suitable outlet or conduit. By reversing said valve the current willnot pass down to the stove L', but will continue along the main pipe and escape into the car through opening D2, which may be provided with a valve.

Two stoves may be employed, and the current sent down to either or both, or to neither, according to circumstances.

The current thus admitted will ventilate the car, supplying it with abundance of pure fresh air, and carrying off the vitiated atmosphere, which latter may escape through the doors, windows, Ventilating-openings, or other outlets.

To prevent an excess of air-pressure in a closed car, one or more passages, M, with outwardly-opening spring-controlled valves m, may be provided as escapes.

The air-outlets from the pipe D in each car will be controlled by the valves, so that the entire volume of air conveyed by said pipe will IOO not escape into the rst car in a train, a due supply being thus provided for each car of a train.

Operation: A train being made up and in 5 motion, the fan E draws air in through one of the front openings, d or d. and forces it back under pressure into the ears, where it is distributed, as already described, bein g heated by the stoves or allowed to escape without heating, according to the temperature desired.

The provision of the fan or blower will secure a positive current at all times when the car is in motion, which current could not be obtained without the fan when the wind, as is frequently the case, is traveling in the same direction as the train and at or about the same rate of speed.

If the road be dry and dusty or wet, the air should be taken in through the opening d; if otherwise, through the more favorable opening d'.

When the platform-couplers are uncoupled and the locomotive, tender,l and cars separated, the air-pipe couplings will automatically open 25 by the mere act of' drawing apart, and will, in

like manner, self-couple whenever a train is made up.

k k show handles whereby the connections for pipe l) may be turned to prevent contact of arms K K.

As already mentioned, Aeither of the openings d d' may be opened alternately. They may also be both closed temporarily by means of the valve d2 when it is desired, in passing a train or under other circumstances, to prevent the admission of air loaded with dust, dac., to pipe D.

What l claim as my invention is- The pipe D, having openings d and d and damper d2, operated from the cab of the engine by means substantially as shown and described.

In testimony that I claim the foregoing I have hereunto set my hand this 20th day of May, isn.

JOHN S. LLOYD.
